Mastering Python for Networking and Security

By: José Ortega

Overview of this book

It’s becoming more and more apparent that security is a critical aspect of IT infrastructure. A data breach is a major security incident, usually carried out by just hacking a simple network line. Increasing your network’s security helps step up your defenses against cyber attacks. Meanwhile, Python is being used for increasingly advanced tasks, with the latest update introducing many new packages. This book focuses on leveraging these updated packages to build a secure network with the help of Python scripting. This book covers topics from building a network to the different procedures you need to follow to secure it. You’ll first be introduced to different packages and libraries, before moving on to different ways to build a network with the help of Python scripting. Later, you will learn how to check a network’s vulnerability using Python security scripting, and understand how to check vulnerabilities in your network. As you progress through the chapters, you will also learn how to achieve endpoint protection by leveraging Python packages along with writing forensic scripts. By the end of this book, you will be able to get the most out of the Python language to build secure and robust networks that are resilient to attacks.

Gathering Information from Servers

Throughout this chapter, we will look at the main modules that allow us to extract information that the servers expose in a public way. With the tools we have discussed, we can get information that may be useful for later phases of our pentesting or audit process. We will see tools such as Shodan and Banner Grabbing, getting information for DNS servers with the DNSPython module, and Fuzzing processing with the pywebfuzz module.

The following topics will be covered in this chapter:

  • Introduction to gathering information
  • The Shodan package as a tool to extract information from servers
  • The Shodan package as a tool for applying filters and searching in Shodan
  • How to extract banner information from servers through the socket module
  • The DNSPython module as a tool for extracting information from DNS servers
  • The pywebfuzz module as a tool for obtaining...
